12 THORNDOWN LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Surrey Heath local authority area over time, sourced from the HPI. The four 12 THORNDOWN LANE sales between June 2012 and March 2020 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the March 2015 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the March 2020 sale, where it rises to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 12 THORNDOWN LANE be worth now?

12 THORNDOWN LANE might now be worth an estimated £571,678.

This is based on house price inflation of 22.4%, between March 2020 and February 2025, for semi-detached houses, in the Surrey Heath local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 22.4% inflationary increase is applied to the most recent sale price for 12 THORNDOWN LANE of £467,000 on 20th March 2020. For the value to have increased from £467,000 to £571,678 over the five years and one month to February 2025, the following assumptions must hold true:

• The value of 12 THORNDOWN LANE has moved in line with the HPI for semi-detached houses in the Surrey Heath local authority area.
• The March 2020 sale price of £467,000 represented a fair market value for the property.
